/design-review
Third-party agent, indexed by constructs.sh. The canonical, maintained version lives in gstack by Garry Tan. This page describes the agent in our own words; it does not reproduce it.
What it does
Audits the implemented design with the same 0-10 dimension scoring as the plan-stage review, then fixes what it finds rather than only reporting.
Where it fits
gstack is an open-source "software factory" that turns a coding agent into a virtual engineering team of about two dozen specialized roles, run through a structured sprint loop: think, plan, build, review, test, ship, reflect. /design-review is one station in that loop.
Note
Renamed upstream to /design-review; the link points at the repo.
Use it
Install gstack from the repository and run /design-review inside your project. Canonical source: https://github.com/garrytan/gstack
